TRENDS MASS TRANSIT NOVEMBER 2018 14 CompositesWorld Applications for pultruded composites in the rail sector are set to grow, according to a new report from the European Pultrusion Technology Assn. (EPTA, Frankfurt, Germany). Lightweight, durable composite materials offer energy-efficient solutions with lower environ- mental impact and reduced life cycle costs in rolling stock and rail infrastructure, according to "Opportunities for Pultruded Composites in the Rail Market." Growing populations, accelerating urbanization, resource scarcity and other drivers are spurring investment in the rolling stock and infrastructure that will be required to create more sustainable and energy-efficient railway systems, says the report. Composites can offer cost-effective alternatives to traditional construction materials like metal or concrete, without compromis- ing safety, and offer benefits including faster train acceleration, increased payload, lower maintenance and customizable solutions. "As international policies continue to push to mitigate CO 2 emissions from global transport activity, demand for lightweight materials such as compos- ites will increase," explains Dr. Elmar Witten, secretary of EPTA. "Increased demand for lightweight, high-perfor- mance, fire-retardant materials for train interiors will favor pultruded components, and proven performance in interior applications over time will strengthen the case for adoption of composites in structural applications. The rail sector's growing focus on life cycle costs is a further factor improving the competitive position of composites against other materials." Pultruded profiles can find applica- tions in external and internal parts, enabling multi-functional design. For example, full-span roof panels are possible, from window to window, with integrated air conditioning ducts and heating channels. Partitions, luggage shelves and storage units, tables, window trims, catering and toilet modules, and door components are also applications for pultruded profiles. Unlike metals, glass fiber composites do not need to be electrically earthed, making them ideal for cable trays, third rail covers, rail joints and trackside cabinets, and ballast retention systems. Further infrastructure applications include railroad ties and embankment shoring systems, tunnel lining panels, access platforms, and fencing and barri- ers.
